Description
Technical Field
The utility model relates to the technical field of auxiliary tools of numerical control lathes, in particular to a rear positioning device of an oil cylinder of a numerical control lathe.
Background
When a numerical control lathe is used for boring an inner hole of an oil cylinder and turning internal and external threads, two positioning modes, namely front positioning and rear positioning, are usually adopted for axial positioning. The front positioning is to fix the length by firmly attaching the depth caliper to the end surface of the hydraulic chuck and firmly attaching the depth caliper to the processing oil cylinder; and then, the positioning is realized by arranging a positioning sleeve in the chuck and firmly positioning the rear end surface of the oil cylinder by the bottom of the positioning sleeve. The front positioning has the advantages of simple and convenient operation, low positioning precision and inaccurate positioning, and the conditions of size out-of-tolerance, high rejection rate and the like often occur in the oil cylinder processing with higher precision requirement. And after the positioning is adopted, the positioning precision is high, and the positioning is accurate. But the hydro-cylinder is processed at every turn the back, need to blow the interior outer iron fillings of hydro-cylinder clean with the air gun, will lead to some iron fillings to be blown into in the position sleeve like this, cause the location inaccurate, the condition that the back location can not be used even.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems mentioned in the above, the utility model provides a rear positioning device for an oil cylinder of a numerical control lathe, which has a simple structure, can prevent iron chips from entering into a positioning sleeve when an air gun blows the iron chips, ensures the positioning accuracy, and further ensures that the rear positioning can be normally used.
The utility model provides a positioner behind numerical control lathe hydro-cylinder, its includes position sleeve, position sleeve is used for inserting the stopper post of treating processing to the barrel head in its section of thick bamboo, its characterized in that: the rear positioning device further comprises a sealing ring and a jacket, the jacket is used for being sleeved on the part, outside the positioning sleeve, of the plug to be processed, and the sealing ring is used for being sleeved on the part, inside the positioning sleeve, of the plug to be processed.
Further, the position of the sealing ring is close to the position of the jacket.
Furthermore, a connecting plate is further arranged on the end face of the opening of the positioning sleeve and is fixedly connected with a hydraulic chuck of a lathe through a screw.
Further, the sealing ring is specifically a rubber O-shaped ring.
The utility model has the beneficial effects that:
according to the utility model, the sealing ring is sleeved on the part of the plug column to be processed in the positioning sleeve, so that when an air gun blows scrap iron, the scrap iron cannot enter the positioning sleeve, the positioning accuracy is ensured, the normal use of the rear positioning device is further ensured, the stability of the processing size is maintained, and the product quality is improved; and because the sealing ring is low in cost, not easy to damage and long in service life, the production cost is saved, and even if the sealing ring is damaged, only one sealing ring with the same specification needs to be replaced again and sleeved on the excircle of the oil cylinder, so that the sealing ring has the advantages of convenience in use, simplicity in operation and the like.

Detailed Description
The present invention will be further described with reference to the following examples.
The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model. The conditions in the embodiments can be further adjusted according to specific conditions, and simple modifications of the method of the present invention based on the concept of the present invention are within the scope of the claimed invention.
Referring to fig. 1-2, a rear positioning device for an oil cylinder of a numerically controlled lathe comprises a positioning sleeve 1, wherein the positioning sleeve 1 is used for inserting a plug 4 to be processed into a cylinder to the bottom of the cylinder, the rear positioning device further comprises a sealing ring 2 and a jacket 3, the jacket 3 is used for being sleeved on the part, outside the positioning sleeve 1, of the plug 4 to be processed, and the sealing ring 2 is used for being sleeved on the part, inside the positioning sleeve 1, of the plug 4 to be processed; the position of the sealing ring 2 is close to that of the jacket 3. The positioning sleeve is characterized in that a connecting plate 5 is further arranged on the end face of the opening of the positioning sleeve 1, and the connecting plate 5 is fixedly connected with a hydraulic chuck of a lathe through a screw. The sealing ring 2 is specifically a rubber O-shaped ring.
When the device is used, the positioning sleeve 1 is inserted into a lathe pull rod hole and fixed with a hydraulic chuck by a screw; then, after a plunger 4 to be processed after plating is sleeved with a sealing ring 2 and a jacket 3, lightly pushing the plunger to the bottom of a positioning sleeve 1, clamping the jacket 3 by using a hydraulic clamping jaw, and starting processing; after the machining is finished, the clamping jaws are loosened, the workpiece is pulled out, and the clamping sleeve 3 and the sealing ring 2 are taken down.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
